You are correct the street is only 4 lanes. But some items to note.
The left lanes are about a car and a half wide which gives us a extra full lane if we combine that space together. This underutilized space can be used for center mediums and larger sidewalks.
In dedicated locations this extra space can then be alternated with dedicated loading and unloading zones provided. Those unloading zones can also be elevated at sidewalk level to allow the the space to be reclaimed by pedestrians when not in use by a car or vehicle.
Example. Parking in designated loading and unloading zones at sidewalk level. When a car in not parking the sidewalk is reclaimed for use by pedestrians.
The intersection at some locations have dedicated left and right lane turns. This allows spaces for dedicated loading platforms at most intersection.
I know the plan is not perfect and the street does seem narrow, but with some cleaver choices in space planing and alternating designs along the corridor it could work.
